IMPROVEMENT IN WATiER-ELEVATORS.

Specification forming part of Letters Patent No. 53,62! dated April 3,1866.

Y hereby declare that the following is a full,

clear, and exact description thereof, which will enable others skilledyin the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specication, in which-Figure l is a side elevation of my improvements. Fig. 2 is a transversevertical section of the same, taken in the plane of the line .fr at',Fig. 1.

Similar letters of reference indicate like parts.

My invention consists in the employment of a friction-wheel of novelconstruction, by which, in combination with a crank, also of novelconstruction,and an automatically-operating pawl, the elevation of thebucket is easily accomplished and the velocity of the descent of thesame is perfectly regulated, one hand being only required to operate theentire thing, whereby should a careless management of the crank takeplace no accident could occur by a too rapid descent of the bucket.

A designates the windlass, having suitable bearings at one end in thewell-curb, and at the other end a plate, B, is attached, which carriesor has formed upon it a series of ratchetteeth, a a, (see Fig. 1,)which, in connection with a pawl, C, provides a means for preventing thewindlass turning in a direction to permit the bucket to descend. Thisplate B has a shaft, I), on one side, which constitutes the journal atthis ,end of the windlass, and it is mounted in suitable bearin gs inthe well-curb. To the other end of this shaft b there is attached afriction-wheel, D, which, in the present instance, has its peripherybeveled outward but this may be a squared face, if desired. In practicethe plate, shaft, and friction-wheel will be cast in one piece, whichwill produce a firm and strong piece of work andreduce the expense ofmanufacture. Through the shaft b there is run a pin, E', which eX- tendsout beyond the friction-wheel D, and upon this there is pivoted thecrank F in such manner that said crank shall have a lateral play, forthe purpose presently to be specified.

Upon one end of this crank there is formed a projection or brake, e,(see Fig. 2,) which is beveled so that its inner face will correspond tothe bevel on the friction-wheel. There is also formed on this crank, onthe other side of the point at which it ispivoted, a lug or pin, d.

The inner face of the friction-Wheel D has recesses formed in it, orarms or catches e (see Fig. l) placed across it, against which the lug ostrikes when it is desired to rotate the windlass.

To the paw] C there is attached a bar or rod, G, which has a bent end,f,so arranged that when the crank is turned in a position with the brake cdownward the said brake will raise it up and thus release the pawl.

The operation of the parts, above described is as follows: When it isdesired to lower the bucket the crank is turned with the handle upward,and by reason of the lateral play which the crank has upon its nut orpin the lug d may be pressed in a direction toward the well-curb, whichat once brings the brake against the bent endf of the rod G, so as todisengage the pawl from the ratchet-wheel. Now the brake is caused topress or bear against the friction-wheel as hard or tightly as desired,and thus the rotation ofthe wheel may be checked, as desired; and itwill be noticed that the moment the said brake is withdrawn from thefriction-wheel the rod G will be permitted to fall down, which willcause thepawl to enga-ge with the teethof the ratchet-Wheel, and thusthe rotation of the windlass is immediately stopped. Thus no accidentcan occur by a careless management of the crank. To draw up the bucket,the lug c is thrown into the recesses and against the arms e upon theface of the friction-wheel, when the windlass can be rotated, andconsequentlythe bucket elevated. The whole operation is simple and easy,one hand only being required to operate this water-elevator, either fordrawing up the bucket or allowing it to descend in' a proper manner, ascan be readily understood.

I am aware that a patent has been issued to Jacob H. Best, dated August8, 1865, wherein a provision for checking the descent of the bucketisshown-namely,a projection is formed on the inner side of the wrench,which can be pressed against the side of the ratchet-wheel, so as tooperate as a brake, and this is the in combination with thefriction-wheel D, pinV E, end plate, B, and windlass A, substantially asspecified.

3. Hanging or pivoting the crank F on a pin, E, which is securedlooselj7 in the friction-Wheel D by the plate B, whereby the crank andpin revolve together for adjusting the brake to the required positionfor arresting the velocity ofthe windlass, substantially as specied.

4. rlhe recesses and arms c in the friction- Wheel D, and inclined asshown, substantially as and for the purpose specified.

5. The lug1 d on the crank F, as arranged in relation to the recessesand arms e in the friction-Wheel D for rotating` the Windlass,substantially as herein specied.

6. The rod Gr, attached to the pawl C,When arranged as described, andused in combination with the projection c on the crank.

rEhe above specification of my invention signed by me this 15th dayofNovember, 1865.
